We describe a new species of the genus from the Khao Laem Mountain, Suan Phung District, Ratchaburi Province, Tenasserim Region, western Thailand, based on molecular and morphological evidences. The new species, sp. nov., can be distinguished from all other congeners by the following combination of characters: (1) adult SVL of 41.4-58.8 mm in males and 54.7-58.6 mm in females; (2) rounded finger and toe tips; (3) relative finger lengths: II<IV<I<III; relative toe lengths: I<II<V<III<IV; (4) toe webbing thick and well developed; (5) inner metatarsal tubercle small; (6) iris bicolored, black ventrally and turquoise dorsally, with light blue sclera; (7) dorsum brown to grey with distinct darker markings edged with brown; (8) belly and limbs ventrally whitish with contrasting confluent black reticulations; (9) tympanum mostly free of dark marking; (10) narrow dark canthal stripe present; (11) lateral row of dark spots absent; (12) limbs dorsally with distinct dark bars; tibia with four to five dark transverse bars; (13) dense dark reticulation or large dark blotch at groin continuing to ventral and posterior sides of thighs; (14) femoral gland in shape of large white blotch; (15) males with single vocal sac, mature males lack lip spinules. Our study provides further evidence for a hidden biodiversity of montane areas of Tenasserim Region on the border of Thailand and Myanmar.
我们基于分子和形态学证据，描述了一种来自泰国西部丹那沙林地区叻丕府川蓬区考累姆山的该属新物种。新物种，[具体物种名] sp. nov.，可通过以下特征组合与所有其他同属物种区分开来：(1)成年雄性的体长为41.4 - 58.8毫米，成年雌性的体长为54.7 - 58.6毫米；(2)指端和趾端圆润；(3)相对指长：II<IV<I<III；相对趾长：I<II<V<III<IV；(4)趾间蹼厚且发育良好；(5)内侧跖突小；(6)虹膜双色，腹侧黑色，背侧绿松石色，巩膜浅蓝色；(7)背部棕色至灰色，有明显的深色斑纹，边缘为棕色；(8)腹部和四肢腹侧为白色，有对比鲜明的融合黑色网状花纹；(9)鼓膜大多无深色斑纹；(10)有狭窄的深色眶上纹；(11)无外侧深色斑点列；(12)四肢背侧有明显的深色条纹；胫骨有四至五条深色横纹；(13)腹股沟处有密集的深色网状花纹或大的深色斑块，延伸至大腿腹侧和后侧；(14)股腺呈大的白色斑块状；(15)雄性有单个声囊，成年雄性无唇小刺。我们的研究为泰国和缅甸边境丹那沙林地区山区隐藏的生物多样性提供了进一步证据。
